daltonize

Automatic colormap adjustment for color-blind users.

This function automatically converts any colormap supplied as an argument into a color-blind-friendly colormap, by adjusting color saturation.

Example of use:

N = 5 ;
colors = parula(N) ;
x = [1:5]' ;
figure("Position",[100 100 400 300]) ;
for i = 1:N
    plot(x,i*x,"-o","Color",colors(i,:),"LineWidth",2,"MarkerFaceColor",colors(i,:)) ;
    hold on ;
end
hold off ;
title("Figure with original parula colormap") ;

colors2 = daltonize(parula(N)) ;
figure("Position",[100 100 400 300]) ;
for i = 1:N
    plot(x,i*x,"-o","Color",colors2(i,:),"LineWidth",2,"MarkerFaceColor",colors2(i,:)) ;
    hold on ;
end
hold off ;
title("Figure with adjusted parula colormap") ;
